Nettet本篇主要讲讲Sklearn中SVM，SVM主要有LinearSVC、NuSVC和SVC三种方法，我们将具体介绍这三种分类方法都有哪些参数值以及不同参数值的含义。 在开始看本篇前你可以看看这篇： 支持向量机详解LinearSVCclass sklearn ... random_state: 随机种子的 ... NettetWhen dual is set to False the underlying implementation of LinearSVC is not random and random_state has no effect on the results. Using L1 penalization as provided by LinearSVC (penalty='l1', dual=False) yields a sparse solution, i.e. only a subset of feature weights is different from zero and contribute to the decision function.

I fix the issue by just setting dual=False and leaving max_iter to its default. With LogisticRegression(solver='lbfgs') classifier, you should increase max_iter. does chase chrisley have a job https://micavitadevinos.com
